Tall Meadow-rue has tall, upright stems and delicate, finely divided blue-green foliage that gives it a soft, airy appearance. In summer, it produces loose clusters of tiny white to greenish-white flowers. Female plants can develop attractive clusters of dangling seeds after flowering. Despite its height, it has a relatively light and airy appearance and does not visually overwhelm neighbouring plants. It forms clumps and is generally well behaved. If grown in rich soil or exposed to strong winds, it may benefit from support. Keep the soil consistently moist, especially during establishment. It is particularly useful where taller plants are needed without creating a dense mass.
